Hi all!
We have PXA255 based platform with WCE42 and we are testing stability of the
platform. Our hardware is not battery backed and we rely on powerdown driver
and TFAT file system. We have noticed that after number of power down and
power up cycles (quite a lot) our platform dies. We have flash resident
persistent registry (hive based). Platform could not start anymore. I am
suspecting that the file-system is corrupted (so the registry too). We are
using msflash strata driver.
Our settings are:
[HKEY_LOCAL_MACHINE\System\StorageManager]
"Dll"="fsdmgr.dll"
"PNPUnloadDelay"=dword:0
; @CESYSGEN IF CE_MODULES_STRATAD
; HIVE BOOT SECTION
; StrataFlash block driver.
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\StrataFMD]
"Dll"="stratad.dll"
"Order"=dword:2
"Prefix"="DSK"
"Ioctl"=dword:4
"Profile"="MSFlash"
"IClass"="{A4E7EDDA-E575-4252-9D6B-4195D48BB865}"
"MemBase"=dword:b9300000
"MemLen"=dword:03000000
"Flags"=dword:1000
; Override names in default profile
[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\MSFlash]
"Name"="MSFLASH for STRATAFLASH"
"Folder"="Storage Card"
[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles]
"AutoMount"=dword:1
"AutoPart"=dword:1
"AutoFormat"=dword:1
; Keep FATFS from trying to shadow \Windows
[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\MSFlash\FATFS]
"MountFlags"=dword:2
[HKEY_LOCAL_MACHINE\System\StorageManager\AutoLoad\MSFlash]
"DriverPath"="Drivers\\BuiltIn\\StrataFMD"
"LoadFlags"=dword:1
"Order"=dword:0
; END HIVE BOOT SECTION
; @CESYSGEN ENDIF CE_MODULES_STRATAD
; @CESYSGEN IF FILESYS_FSREGHIVE
; HIVE BOOT SECTION
[HKEY_LOCAL_MACHINE\init\BootVars]
"SYSTEMHIVE"="Registry\\system.hv"
"PROFILEDIR"="Registry"
"Start DevMgr"=dword:1
"DefaultUser"="Iskraemeco"
;Causing some debugchk's in debug version,
;performance monitoring tools doesn't work.
;RegistryFlags"=dword:1
; END HIVE BOOT SECTION
; @CESYSGEN ENDIF FILESYS_FSREGHIVE
[HKEY_LOCAL_MACHINE\System\StorageManager\FATFS]
"FriendlyName"="FAT FileSystem"
"Dll"="fatfsd.dll"
;"Flags"=dword:00000024
"Flags"=dword:007C0028
"Paging"=dword:1
"EnableCache"=dword:1
"CacheSize"=dword:0
"Util"="fatutil.dll"
"FormatTfat"=dword:1
; END HIVE BOOT SECTION
; @CESYSGEN ENDIF CE_MODULES_FATFSD
Any help would be more then welcome.
Thanks, Jernej
